摘要:
The present invention provides methods, compositions, kits, systems and apparatus that are useful for multiplex PCR of one or more nucleic acids present in a sample. In particular, various target-specific primers are provided that allow for the selective amplification of one or more target sequences. In one aspect, the invention relates to target-specific primers useful for the selective amplification of one or more target sequences associated with cancer or inherited disease. In some aspects, amplified target sequences obtained using the disclosed methods, kits, systems and apparatuses can be used in various downstream processes including nucleic acid sequencing and used to detect the presence of genetic variants.
摘要:
Methods and systems for quantification of a target nucleic acid in a sample are provided. The method includes forming a plurality of discrete sample portions. Each of the plurality of discrete sample portions comprising a portion of the sample, and a reaction mixture. The method further includes amplifying the plurality of discrete sample portions to form a plurality of discrete processed sample portions. At least one discrete processed sample portion containing nucleic acid amplification reaction products. Fluorescence signals are detected from the at least one of the plurality of discrete processed sample portions to determine a presence of the at least one target nucleic acid. The method also includes determining the respective volumes of the plurality of the plurality of discrete processed sample portions, and estimating the number of copies-per-unit-volume of the at least one target nucleic acid in the sample. Estimating the number of copies-per-unit-volume is based on the number of discrete processed sample portions determined to contain the at least one target nucleic acid therein.
摘要:
Methods for determining the methylation state of at least one target nucleotide that employ a reaction catalyzed by a structure-specific nuclease, typically coupled with a ligation reaction are disclosed. By detecting the cleaved flap, a ligation product, a ligation product surrogate, a hybridization complex, or combinations thereof, one can infer the degree to which the corresponding target nucleotide is methylated. Certain of the disclosed methods are particularly useful for evaluating bisulfite-treated target sequences and determining the degree of target nucleotide methylation. The disclosed methods are well suited for rapidly analyzing a large number of target sequences, typically in one or more multiplex reactions. Kits for performing coupled nuclease and ligase methylation detection assays are also disclosed.
摘要:
The present teachings pertain to methods, reaction mixtures, and kits for ligating polynucleotides. In some embodiments, a heat-activatable ligation agent, a phosphorylation agent, and a decontamination agent are included in the same ligation reaction mixture with at least one probe set, at least one linker set, and at least one target polynucleotide. A reaction at a first temperature results in hybridization of the probes to the target, phosphorylation of the probes, and decontamination of unwanted reaction components. A reaction at a second temperature results in the ligation of the probes together. In some embodiments, the present teachings are applied in highly multi-plexed ligation reactions in which a plurality of single nucleotide polymorphisms in a plurality of target polynucleotides are queried, and eventually detected using a mobility dependent analysis technique.
